Product details

4 MHz GBW with rail-to-rail output

The TS921ID is a single-circuit general-purpose op-amp from STMicroelectronics, offering a 4 MHz gain-bandwidth product and a 1.3 V/µs slew rate — enough bandwidth for audio-frequency filtering, sensor conditioning, and control-loop compensation in industrial and automotive signal chains.

DC precision and input characteristics

Input offset voltage is 3 mV maximum — adequate for general-purpose gain stages where the signal is several hundred millivolts or more, but worth derating if the front-end sensor output is below 10 mV full-scale. Input bias current of 15 nA typical means the voltage error across a 10 kΩ source resistor is 150 µV — negligible for most applications, but a high-impedance source above 100 kΩ will see a noticeable offset that may require a lower-bias op-amp.

Supplied in tube packaging, suitable for low-volume assembly or prototyping; for reel-fed production, order the tape-and-reel variant if available.

RoHS3 compliant (ROHS3), meeting the latest EU restriction directive for lead and other hazardous substances.

Frequently asked questions

When sourcing TS921ID, what's the closest functional second-source — TS922IDT?

The TS922IDT is a dual-channel version (two amplifiers in one package) with identical per-channel specs: 4 MHz GBW, 1.3 V/µs slew rate, rail-to-rail output, same supply range and temperature grade. It also carries AEC-Q100 automotive qualification. If your BOM needs two amplifiers, the TS922IDT consolidates the count; for a single-channel drop-in, the TS921ID remains the direct fit.

What is TS921ID's listed slew rate?

The slew rate is 1.3 V/µs, which defines the maximum rate of change at the output for large-signal steps — adequate for audio and control loops up to several hundred kilohertz.

What compliance documentation does STMicroelectronics provide for TS921ID?

The TS921ID is RoHS3 compliant (ROHS3). STMicroelectronics provides the standard declaration of conformity and material composition data upon request through the supply chain.
